Spatial CSIT Allocation Policies for Network MIMO Channels

  title={Spatial CSIT Allocation Policies for Network MIMO Channels},
  author={Paul de Kerret and David Gesbert},
  journal={IEEE Transactions on Information Theory},
In this paper, we study the problem of the optimal dissemination of channel state information (CSI) among K spatially distributed transmitters (TXs) jointly cooperating to serve K receivers. One of the particularities of this paper lies in the fact that the CSI is distributed in the sense that each TX obtains its own estimate of the global multiuser MIMO channel with no further exchange of information being allowed between the TXs. Although this is well suited to model the cooperation between…

Generalized degrees-of-freedom of the 2-user case MISO broadcast channel with distributed CSIT
The GDoF result is derived and it is obtained that by specific accounting of the pathloss information, it becomes possible for the decentralized precoded network to reach the same performance as a genie-aided centralized network where the central node has obtained the estimates of both TXs.
C-RAN Zero-Forcing with Imperfect CSI: Analysis and Precode\&Quantize Feedback
A new CSI sharing scheme is proposed that drastically reduces the significant overhead associated with acquiring global CSI for joint transmission and applies a local precoding matrix that creates low-dimensional effective channels that can be quantized more accurately with fewer bits.
On the Total Energy Efficiency of Cell-Free Massive MIMO
This work considers the cell-free massive multiple-input multiple-output (MIMO) downlink, where a very large number of distributed multiple-antenna access points (APs) serve many single-ant antenna users in the same time-frequency resource, and derives a closed-form expression for the spectral efficiency taking into account the effects of channel estimation errors and power control.
Coordinated MultiPoint Transmission with Incomplete Information Precoding and scheduling algorithms for efficient backhauling in cellular networks
The main problem of simultaneously mitigating interference and achieving efficient backhauling is addressed with a layered approach and the physical (PHY) layer precoding approach solves the problem and allowes the medium access control (MAC) layer scheduler to be simple.


CSI feedback allocation in multicell MIMO channels
In this work1, we consider the joint precoding across K transmitters (TXs), sharing the knowledge of the user's data symbols being transmitted to K single-antenna receivers (RXs). We consider a
Degrees of Freedom of the Network MIMO Channel With Distributed CSI
A distributed channel state information (DCSI) model where each TX has its own local estimate of the overall multiuser MIMO channel and must make a precoding decision solely based on the available local CSI, and advocates the use of hierarchical quantization of the CSI.
Rate loss analysis of transmitter cooperation with distributed CSIT
This work focuses on an extension of the conventional centralized CSI at the TX (CSIT) model, where instead of having a single channel estimate, or quantized version, perfectly shared by all the TX antennas, each TX receives its own estimate of the global multiuser channel.
Team decision for the cooperative MIMO channel with imperfect CSIT sharing
This work considers the problem of joint MIMO precoding across multiple distant cooperating transmitters, and presents some solutions to theproblem of beamforming design in this case and illustrates the benefits in practical network scenarios.
Decentralized Precoding for Multicell MIMO Downlink
This paper proposes distributed precoding techniques for the multicell MIMO downlink that are both decentralized with respect to the BSs as well as capable of enabling multiple users to share the same frequency carrier spatially within each cell.
CSI sharing strategies for transmitter cooperation in wireless networks
This article addresses a "Who needs to know what?" problem when it comes to CSI at cooperating transmitters by suggesting that CSI overhead can be contained for even large networks provided the allocation of feedback to TXs is made non-uniform and to properly depend on the network's topology.
The Degree-of-Freedom Regions of MIMO Broadcast, Interference, and Cognitive Radio Channels With No CSIT
Providing robust no-CSIT schemes that have the same DoF as their previously found CSIT counterparts and identifying situations where CSI feedback to transmitters would provide gains that are significant enough that even the DoF could be improved are identified.
Adaptive Limited Feedback for Sum-Rate Maximizing Beamforming in Cooperative Multicell Systems
A new limited feedback strategy is proposed for multicell beamforming where cooperation is restricted to sharing only the CSI of active users among base stations, and a new feedback-bit allocation strategy, to partition the available bits between the desired and interfering channels, is developed.
On multicell cooperative transmission in backhaul-constrained cellular systems
This paper considers the cellular downlink and provides a comprehensive summary and extension of previous and current work on multicell signal processing, and compares the performance obtained through centralized or decentralized optimization approaches, or through optimal or suboptimal calculation of precoding matrices, and identifies reasonable performance–complexity trade-offs.
Inner Bound on the GDOF of the K-User MIMO Gaussian Symmetric Interference Channel
The K-user multiple input multiple output (MIMO) Gaussian symmetric interference channel where each transmitter has M antennas and each receiver has N antennas is studied from a generalized degrees of freedom (GDOF) perspective and the HK-scheme outperforms other schemes and is found to be GDOF optimal in many cases.
